The fluorite fluoresces white when exposed to long wave ultraviolet light as shown in the first image.

The fluorite in the specimen fluoresces a light blue-white under short wave ultraviolet light. Under both fluorescent lights there is kind of a halo within the crystals along the crystal edge. The purple color is the reflection of the lights off the light colored matrix.

The fluorite crystals are an amber color under normal lighting. To see a photo of this material under normal lighting click the link: "To view specimen material from Ohio," in the fluorescent section.
